What Abbott (1974) and many others have called
Eudolium crosseanum (di Monterosato, 1869) is actually E. bairdii
(A. E. Verrill and S. Smith, 1881), and Abbott's E. thompsoni
McGinty, 1955 is actually E. crosseanum (di Monterosato, 1869)!!
E. thompsoni is a synonym of E. crosseanum (di Monterosato)
but not of E. crosseanum of authors (E. bairdii ), which
latter species is more common and widespread in the W. Atlantic. See
